To find the total square footage of a rectangle, you would multiply the length by the width. In this case, 28 x 80 equals 2240 square feet. So, there are 2240 square feet in a rectangle with dimensions of 28 feet by 80 feet.
80 x 50 inches is about 28 (27.777) square feet.
80*80 = 6400 square feet
44.4 square feet.
80 acres = 3,484,800 square feet
80 m2 equates to about 861.11 square feet.
80 feet x 8 feet = 640 square feet.
32 feet times 80 feet = 2,880 square feet
16 feet x 80 feet = 1,280 square feet.
960 square feet (12 x 80 = 960).
You would need a total of 80 square yards - you would have a piece 24 feet by 2 feet left over.
1600 square feet 20 x 80 = 1600
You have to multiply the two numbers to get the square footage. In this problem the results will be 6,400 square feet.
